... The genus Trachelyopterus has been a subject of controversy for over two centuries, characterized by ongoing discussions and taxonomic reviews, largely driven by the morphological similarities among its species (Akama 2004). While some authors have affirmed its validity as a distinct genus (Mees 1974;Curran 1989;Royero 1999;Akama 2004;Birindelli 2010), others have treated it as synonymous with other genera, such as Parauchenipterus (Ferraris 1988(Ferraris , 2003, Auchenipterus Valenciennes, 1840 (Günther 1864) and Trachycorystes Bleeker 1858 Eigenmann 1888, 1890;Regan 1911;Miranda-Ribeiro 1911;Britski 1972). In this context, cytogenetic studies can provide new information that can contribute to the taxonomy and enhance discussions concerning the evolutionary and biogeographic aspects of Trachelyopterus species. ...
Trachelyopterus Valenciennes 1840 species exhibit striking morphological and cytogenetic similarities, leading to persistent taxonomic challenges. This research focuses on Trachelyopterus galeatus Linnaeus 1766 and Trachelyopterus porosus Eigenmann & Eigenmann 1888, both widely distributed throughout South America and often sympatric, facilitating cytogenetic comparisons. These taxonomic entities are noteworthy for their extensive geographical ranges within the genus. We examined two populations of T. galeatus and T. porosus collected from sympatric sites in the Amazon and Pantanal regions. Both species had the same diploid number and simple Ag-NORs. The 18S rDNA sites were found in only one subtelocentric chromosome pair. Meanwhile, the 5S rDNA sites were found on two distinct chromosomal pairs, with differences in the chromosomal morphology and site position among the species, constituting the most efficient chromosomal marker to distinguish them. The 5S rDNA pattern differed between species but remained consistent between populations of the same species. Minor differences were observed between the T. galeatus populations, probably related to chromosomal rearrangements. In contrast, despite the considerable geographical distance, no cytogenetic differences were detected among the T. porosus populations. Overall, the congruence between cytogenetic and morphological characteristics, combined with our findings from sympatric samples and existing data from geographically separated populations of Trachelyopterus, indicates that the cytogenetic is a promising tool for species differentiation and for delving into the cytotaxonomic and evolutionary aspects of Auchenipteridae.

This book provides comparative data on fish ecology and small-scale fisheries between Tapajos (clear water) and Negro (black water) rivers, in the Brazilian Amazon. These rivers are less studied than white water rivers and few books on Amazon fishes have addressed more than one river basin. These data can serve as a baseline to check future changes or impacts in these rivers, which can be affected by development projects, such as highways, deforestation, mining and dams. Besides information on fish biology, the book also discusses fish uses, fisheries and its importance for riverine people, comparing these data for each fish species between sites located inside and outside conservation units. The book is an outcome of the research project ‘Linking sustainability of small-scale fisheries, fishers’ knowledge, conservation and co-management of biodiversity in large rivers of the Brazilian Amazon’, which was coordinated by the editor of this volume and funded by United States Agency for International Development (USAID) and National Academies of Science, Engineering and Medicine (NAS).
... Immature Tatia Ribeiro 1911 can be diagnosed from other auchenipterid genera by having a shorter anal fin with seven to 11 branched rays Ponton & Mérigoux, 2001) v. 32-48 branched rays in Auchenipterus and 20-30 branched rays in Trachelyopterus Valenciennes 1840 (Santos et al., 1984;Nakatani et al., 2001). Fin-ray meristics of Centromochlus Kner 1858 are similar to those of Tatia, but these genera differ in the length of the anal-fin base and the height of the caudal peduncle: T. intermedia has a short anal-fin base (between 3·3 and 8·0% of L S ) and height of the caudal peduncle (between 10·1 and 18·6% of L S ) whereas Centromochlus has a longer anal-fin base (>8% of L S ) and height of the caudal peduncle (<10% of L S , Birindelli, 2010). ...
This study describes the morphology, morphometry and meristic characters of larval and juvenile Tatia intermedia collected in the middle Tocantins River and some of its tributaries. Six larvae of T. intermedia were examined and they have a moderately elongate body, head slightly dorso-ventrally depressed with a convex snout, small and round eyes and a subterminal mouth. In five juvenile stages observed, the head and eye are relatively smaller than in the larval stage and the snout remains convex and mouth becomes terminal.
... Auchenipterus osteomystax (Ribeiro, 1918) Auchenipteridae pela nadadeira anal longa (> 35 raios), por apresentar apenas um par de barbilhões mentonianos, e por ter de 9-11 raios ramificados na nadadeira peitoral e 9-12 raios ramificados no lobo ventral da nadadeira caudal (Birindelli, 2010). A espécie pode ser diferenciada das duas espécies congêneres por apresentar uma margem serrada na porção distal do barbilhão mandibular, pela palidez da porção ventral, com cromatóforos esparsos (vs. ...

O Lago Batata pertence à bacia do rio Trombetas e se localiza no município de Oriximiná, PA. Durante uma década, recebeu efluentes ricos em rejeito argiloso devido a atividades de mineração de bauxita, que resultou em alterações paisagísticas, limnológicas e biológicas. Em 1989 cessou a emissão de rejeito e se iniciou um monitoramento que tem gerado informações sobre a influência do distúrbio nas características abióticas e bióticas do Lago Batata, incluindo a fauna de peixes. Este trabalho objetivou: i) produzir um inventário ictiofaunístico atualizado, considerando variações interanuais; ii) avaliar se há diferenças na estrutura taxonômica e na composição da ictiofauna entre as áreas com Rejeito e Natural do lago; iii) observar se houve variação na estrutura taxonômica e filogenética da ictiofauna ao longo dos últimos vinte anos de monitoramento. Coletas foram realizadas com baterias de rede de espera com malha variada em áreas afetadas e não afetadas pelo rejeito, com frequência trimestral de 1990 a 1993 e anual de 1997 em diante. Foram capturados 18.980 indivíduos, agrupados em nove ordens, 31 famílias e 159 espécies. Houve um alto número de singletons (11) e doubletons (12), e foram estimadas de 163 a 173 espécies no lago, mas apenas 54-93 por coleta. Isso ressalta a importância das espécies raras e do turnover temporal para a diversidade do lago. Não se observou diferenças na riqueza, equabilidade e diversidade entre as áreas, mas a composição ictiofaunística foi diferente entre as áreas (ANOSIM; R = 0,25; p < 0,001) devido a diferenças na abundância das espécies. As diferenças na utilização das áreas se devem à interação entre o nicho das espécies/clados e às modificações causadas pela deposição do rejeito de bauxita. Quando analisada a variação interanual, observou-se a diminuição da dominância na área com Rejeito ao longo dos vinte anos analisados, bem como um aumento na similaridade entre as duas áreas quanto à dominância e equabilidade (0,19 < R² < 0,30; p < 0,05). A diversidade filogenética da área Natural foi maior do que da área com Rejeito (teste t; p < 0,05) e a razão entre os valores de diversidade filogenética entre as duas áreas mostrou aumento da similaridade na diversidade filogenética ao longo do tempo, o que reflete a reestruturação do igapó na área assoreada. Além disso, observou-se que a perda de diversidade filogenética ocorreu em consonância com o aumento da dominância, sugerindo que os efeitos do rejeito de bauxita no Lago Batata não se deram com a perda de espécies ou clados, mas sim através da reestruturação da comunidade.
... Information about the anatomy of the Doradidae is mostly derived from phylogenetic studies (Higuchi, 1992;Sabaj, 2002;Birindelli, 2006Birindelli, , 2010Birindelli, , 2014Sousa, 2010). Higuchi (1992) presented a detailed description of the osteology of Wertheimeria maculata and Diogo et al. (2004) reviewed osteology and myology of the cephalic region and pectoral girdle of Franciscodoras marmoratus by comparing it to Anadoras weddellii, Acanthodoras cataphractus, and Ossancora punctata. ...
This paper reports the results of a comparative study of the mandibular, hyoid, and pectoral musculature of South American Doradidae. Sixty-one species of Doradidae were examined including representatives of all the genera. Twenty muscles are described including their ontogenetic origin, function, area of origin and insertion, and parts. Seven muscles from the cranial region: adductor mandibulae, extensor tentaculi, levator arcus palatini, dilatator operculi, levator operculi, adductor operculi, and adductor arcus palatini; six muscles from the ventral region: intermandibularis, protractor hyoidei, hyohyoides inferioris, hyohyoidei abductores, hyohyoidei adductores, and sternohyoideus; and seven muscles from the pectoral fin: adductor superficialis, adductor profundus, abductor superficialis, abductor profundus, arrector ventralis, arrector dorsalis, and abductor rotator. Comparisons between Doradidae and other catfish families (e.g. Auchenipteridae, Aspredinidae) were made in order to understand and establish variations in position and shape of different muscles. A muscle not previously described for the pectoral fin of catfishes is described and named here as abductor rotator.
... The higher family-group relationships of taxa within the Auchenipteridae, inclusive of what has been hypothesized as a monophyletic clade uniting species of Tympanopleura, Ageneiosus, and Tetranematichthys Bleeker, has a complex history as a result of early classification schemes and many landmark revisionary and phylogenetic studies of doradoid catfishes in recent decades (e.g., Britski, 1972;Ferraris, 1988;Curran, 1989;Walsh, 1990;Higuchi, 1992;Royero, 1987Royero, , 1999; de Pinna, 1993;Soares-Porto, 1996Ferraris & Vari, 1999;Akama, 2004;Moyer et al., 2004;Ferraris et al., 2005;Vari & Ferraris, 1998Sarmento-Soares & Martins-Pinheiro, 2008;Birindelli, 2010Birindelli, , 2014Sousa, 2010;Ribeiro, 2011;Arce et al., 2013). The multifaceted history of intra-and inter-familial classifications of auchenipterids was reviewed in detail by de Pinna (1998) and Soares-Porto (1998). ...
The Neotropical catfish genus Tympanopleura, previously synonymized within Ageneiosus, is revalidated and included species are reviewed. Six species are recognized, two of which are described as new. Tympanopleura is distinguished from Ageneiosus by having an enlarged gas bladder not strongly encapsulated in bone; a prominent pseudotympanum consisting of an area on the side of the body devoid of epaxial musculature where the gas bladder contacts the internal coelomic wall; short, blunt head without greatly elongated jaws; and smaller adult body size. Species of Tympanopleura are distinguished from each other on the basis of unique meristic, morphometric, and pigmentation differences. Ageneiosus melanopogon and Tympanopleura nigricollis are junior synonyms of Tympanopleura atronasus. Tympanopleura alta is a junior synonym of Tympanopleura brevis. A lectotype is designated for T. brevis. Ageneiosus madeirensis is a junior synonym of Tympanopleura rondoni. Tympanopleura atronasus, T. brevis, T. longipinna, and T. rondoni are relatively widespread in the middle and upper Amazon River basin. Tympanopleura cryptica is described from relatively few specimens collected in the upper portion of the Amazon River basin in Peru and the middle portion of that basin in Brazil. Tympanopleura piperata is distributed in the upper and middle Amazon River basin, as well as in the Essequibo River drainage of Guyana.
... The first bone of the infraorbital series is herein referred to as infraorbital 1 (replaces lacrimal of . It is formed from a single ossification (Birindelli, 2010), and includes the antorbital and infraorbital branches of the infraorbital canal. Some authors (e.g., Arratia & Huaquín, 1995) have considered this bone homologous with the antorbital of Characiformes, which does not bear a canal (Weitzman, 1962). ...
... The genera Agamyxis and Acanthodoras were recovered as sister taxa and deeply nested within the Astrodoradinae in the present analysis, a result that corroborates the previous findings of Birindelli (2010) and Sousa (2010). However, this hypothesis contradictes the findings of Higuchi (1992) and the limits of the Astrodoradinae according to Higuchi et al. (2007), which did not include Acanthodoras and Agamxis. ...
A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae), as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysus and Liosomadoras, and Pseudotatia and Pseudauchenipterus, respectively, and two large ones with the remaining genera. Within the Doradidae, parsimony analysis recovered Wertheimeria as sister to Kalyptodoras, composing a clade sister to all remaining doradids, which include Franciscodoras and two monophyletic groups: Astrodoradinae (plus Acanthodoras and Agamyxis) and Doradinae (new arrangement). Wertheimerinae, new subfamily, is described for Kalyptodoras and Wertheimeria. Doradinae is corroborated as monophyletic and composed of four groups, one including Centrochir and Platydoras, the other with the large-size species of doradids (except Oxydoras), another with Orinocodoras, Rhinodoras, and Rhynchodoras, and another with Oxydoras plus all the fimbriate-barbel doradids. Based on the results, the species of Opsodoras are included in Hemidoras; and Tenellus, new genus, is described to include Nemadoras trimaculatus, N. leporhinus and Nemadoras ternetzi. Due to conflicting hypotheses of the phylogenetic position of Acanthodoras, Agamyxis, and Franciscodoras, these are considered as incertae sedis in Doradidae. All suprageneric taxa of the Doradoidea are diagnosed based on synapomorphic morphological characteristics.
... Osteological data from some species poorly represented in ichthyological collections were obtained from radiographs (indicated as "R" in the Comparative Material section). Nomenclature of osteological elements is based on Fink & Fink (1981), Arratia (2003) and nomenclatural suggestions by Britto (2002) and Birindelli (2010). Most names are explained in The Zebrafish Information Network (ZFIN, 2012). ...
... Comments on Glanidium bockmanni. Glanidium is recognized as a monophyletic clade and regarded as the sister group to other centromochlin genera (Soares-Porto, 1998;Birindelli, 2010). We observed that the small-sized G. bockmanni, is remarkably distinct from the large-sized Glanidium species. ...
Glanidium botocudo, new species, is described from the tributaries to the upper rio Doce and Mucuri, eastern Minas Gerais State, Brazil. It represents the northernmost record of a centromochlin catfish from the coastal rivers of the Northeastern Atlantic Forest. Glanidium botocudo is readily distinguished from its congeners, except Glanidium albescens, by the whitish grey body coloration with evenly spaced small dark brown dots. The new species has a long sharpened ventral process on the urohyal, an uncommon condition among congeners, and the lowest vertebral count among the large-sized Glanidium, 36-37. It differs from Glanidium albescens by proportional measurements and higher number of ribs. Glanidium botocudo and Glanidium albescens are probably sister species, exhibiting similar morphological features and a complimentary distribution pattern, associated to an allopatric distribution pattern. Glanidium bockmanni is transferred to the genus Centromochlus
... The family comprises 20 genera and about 90 species (Ferraris Jr 2007 ), 74 of which have already been registered in Brazil (Akama and Sarmento-Soares 2007). According to Ferraris Jr (2003), Auchenipteridae is subdivided in two subfamilies, Centromochlinae and Auchenipterinae, which form monophyletic groups (Birindelli 2010). Most of the Auchenipteridae genera belong to the subfamily Auchenipterinae, with only Centromochlus Kner, 1857, Gelanoglanis Böhlke, 1980, Tatia Miranda Ribeiro, 1911 and Glanidium Lütken, 1874 allocated in Centromochlinae (Soares-Porto 1998). ...
Auchenipteridae is divided in two subfamilies, Centromochlinae and Auchenipterinae. Centromochlinae has 31 valid species, from which 13 are included in the genus Tatia Miranda Ribeiro, 1911. Among these, Tatia jaracatia Pavanelli & Bifi, 2009 and Tatia neivai (Ihering, 1930) are the only two representative species from the Paraná-Paraguay basins. This study aimed to analyze cytogenetically these two species and thus provide the first chromosomal data for the genus. Although Tatia jaracatia and Tatia neivai presented 2n=58 chromosomes, some differences were observed in the karyotypic formula. The heterochromatin was dispersed in the centromeric and terminal regions of most chromosomes of Tatia jaracatia, and only in the terminal region of most chromosomes of Tatia neivai. The AgNORs were detected in the subtelocentric pair 28 for both species, which was confirmed by FISH with 18S rDNA probe. The 5S rDNA sites were detected in four chromosome pairs in Tatia jaracatia and three chromosome pairs in Tatia neivai. Both species of Tatia presented great chromosomal similarities among themselves; however, when compared to other species of Auchenipteridae, it was possible to identify some differences in the karyotype macrostructure, in the heterochromatin distribution pattern and in the number and position of 5S rDNA sites, which until now seems to be intrinsic to the genus Tatia.
... Com isso, o número de espécies válidas da família deve alcançar uma centena nos próximos anos. O monofiletismo de Doradidae foi inferido por vários autores ( Higuchi, 1992;Moyer et al., 2004;Birindelli, 2010 ...
